Muscle Car Sound. Giving your 2011-2014 GT500 Mustang a menacing muscle car growl and a small but welcome jolt of extra power, the MBRP 3-inch Catted H-Pipe replaces the stock connection between headers and exhaust system, including the catalytic converter. The wide-open mandrel bent design helps clear fumes and backpressure out of the engine, generating a dyno-tested and proven +18 horsepower and +11 ft/lbs of torque over and above anything an aftermarket cat-back and/or headers produces. This MBRP H-Pipe also gives your vehicle's exhaust note a pleasingly throaty growl. The high flow also helps reduce engine heat for boosted longevity.

Quality Construction. MBRP designed the 3-inch Catted H-Pipe for durability, using T304 stainless steel throughout due to the grade's high resistance to heat and corrosion. The part includes a pair of high-flow catalytic converters (not California legal) and includes rear O2 (oxygen) sensor harness extensions to keep the exhaust system working correctly. The slick high polish of the h-pipe helps to keep road matter from clinging to it and makes cleaning easier when needed - as well as looking good.

Bolt-On Fitment. The MBRP Catted H-Pipe is designed to bolt on to your 'Stang without the need for cutting or welding. Hand tools are sufficient to install this part. The H-Pipe uses factory hangers, and the kit includes all clamps and hardware needed. Installation takes approximately 2 hours.

Application. The MBRP 3-inch Catted H-Pipe is made for application to 2011-2014 GT500 Mustangs.

      Will this trigger a check engine light? I bought a JBA from you and have emissions passing problems now in NY state

      • This MBRP 3 in. Catted H-Pipe utilizes high flow cats, and it may still trigger a check engine light if they are too high flow. Depending on your states regulations, high flow cats may not pass the emissions test.
